Here is a guide to rolling back Fallout 4 Game of the Year Edition to 1.10.163.0 (the version before the "Next Gen Update") 

Do keep in mind that you can also just grab Fallout 4: Game of the Year Edition DRM-free on GOG and skip all this process, while also having the ability to rollback anytime you want hassle-free, play offline, and store your games and their Backup Offline Installers externally.

To get started, install the English version of Fallout 4: Game of the Year Edition via Steam.

Before starting this process, you should disable Steam Cloud Saves to avoid causing problems with your vanilla game saves.

* These files will download into your Steam library folder (by default it is "C:\Program Files (x86)\Steam\steamapps\content\app_377160") in separate depot folders, for example, the Fallout 4 executable file would be in a folder named "depot_377162".
* Once you have these files downloaded, create a new folder on your desktop, and copy the contents of each of the aforementioned folders into this new folder replacing files as you go.
* Once you are done, it means you have constructed the entirety of the previous version of Fallout 4: Game of the Year Edition. Placing these files in the a clean target Fallout 4 folder will allow access to a 1.10.163.0 (pre next gen update) executable.
